SUMMARY:Hermes: a Multi-Tiered Distributed I/O Buffering System for HDF5
DESCRIPTION:Poster\nTech Program Reg Pass, Exhibits Reg Pass\n\nHermes: a 
 Multi-Tiered Distributed I/O Buffering System for HDF5\n\nDevarajan\n\nHig
 h-Performance Computing (HPC) systems’ increasing ability to run data-inte
 nsive problems at larger scale and resolution has driven the evolution of 
 modern storage technologies. In addition, extreme amounts of data are coll
 ected by large scientific instruments and sensor network is resulting in a
  push for more capable storage systems. Hierarchical Data Format (HDF) tec
 hnologies  address the problems of how to organize, access, analyze, and p
 reserve data in the face of enormous growth in size and complexity. To mit
 igate this I/O performance bottleneck, modern storage subsystems are going
  through extensive changes, by adding additional levels of memory and stor
 age in a hierarchy. In this work, we present Hermes: a new, heterogeneous-
 aware, multi-tiered, dynamic, and distributed I/O buffering system for HDF
 5. Hermes enables, manages, and supervises I/O buffering in DMSH. We teste
 d our solution on Cori and show Hermes can accelerate applications by 62x 
 than the state of the buffering platform.
